Can you fail the 9th grade if you fail one class? For example a class like Keyboarding and Applications.

Step-by-step explanation:

If you fail a required class, you must repeat it. You can do that either in summer school or retake it. If you fail an elective, you don't have to repeat it. You need 29 credits to graduate, so it is possible to fail three classes and still graduate with your class if you don't go to summer school.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
